TAMA 300

TAMA 300 ^[1] ihe nchọpụta nke ebili mmiri nke dị na ụlọ akwụkwọ Mitaka nke National Astronomical Observatory nke Japan. Ọ bụ ọrụ nke otu ọmụmụ gravitational wave na Institute for Cosmic Ray Research (ICRR) nke Mahadum Tokyo. E hiwere ICRR na 1976 maka ọmụmụ ihe gbasara mbara igwe, ma na-etolite ugbu a Kamioka Gravitational Wave Detector (KAGRA).

TAMA 300 bu ụzọ na Mitaka site na prototype TAMA 20 nke 20m n'afọ 1991-1994. Mgbe e mesịrị, a kwagara prototype ahụ n'okpuru ala na Kamioka mine ma nye ya aha LISM. Ọ rụrụ ọrụ 2000-2002 ma guzobe ịdị jụụ nke ala ọma jijiji nke ebe dị n'okpuru ala.

Iwu nke ọrụ TAMA malitere na 1995. A chịkọtara data site na 1999 ruo 2004. Ọ nabatara Fabry-Pérot Michelson interferometer (FPMI) na ike recycling. A maara ya dị ka 300m Laser Interferometer Gravitational Wave Antenna n'ihi na ọ nwere ogwe aka 300m ogologo (optical).

Ebumnuche nke oru ngo a bụ imepụta usoro dị elu achọrọ maka interferometer nha kilomita n'ọdịnihu yana ịchọpụta ebili mmiri ndọda nwere ike ime na mberede n'ime otu mpaghara.

Akwụsịla nleba anya TAMA, wee kwaga ọrụ na 100m Cryogenic Laser Interferometer Observatory (CLIO) prototype na Kamioka mine. 

ọ na-erule 2020, a na-eji TAMA 300 gbanwere agbanwe eme ihe dị ka ebe nnwale iji mepụta teknụzụ ọhụrụ.^[2]
